Window Replacement in Federal Way
When a window has reached the end of its useful life, we replace it with one sized to the opening, sealed against wet winters and finished cleanly inside and out. If a repair would serve you better, we tell you that first.

When replacing a window is the right call
Most windows give years of warning before they fail. A sticky sash or a worn weatherstrip is usually a repair. A frame that has rotted at the sill, glass that has lost its seal across several units, or aluminum frames that run with condensation every morning are different. At that point, new parts are going into a window that will keep letting you down.
We start every visit by looking at what can be saved. If the frames are sound, our Window Repair work may buy you many more seasons. When replacement makes more sense, we explain why, show you photos of what we found, and help you choose a window that suits the house and is simple to look after.
What our window replacement includes
Measuring every opening
Older homes settle, and openings are rarely square. We measure each one at several points so the new unit fits without forcing or oversized gaps.
Retrofit or full-frame install
If the existing frame is solid and dry, an insert window can go in with less disturbance to trim and walls. If there is rot or failed flashing, we remove the frame down to the rough opening and rebuild what needs it.
Flashing, insulation and sealing
Each window is shimmed level, insulated with low-expansion foam and flashed so water sheds outward. This is the part you never see, and it decides how long the window lasts.
Glass and frame choices
We go over vinyl, fiberglass and wood-clad options, low-E coatings and tempered glass where code calls for it, such as near tubs or doors. You get the trade-offs plainly, including how much upkeep each one asks of you.
Interior and exterior finish
New casing, sill trim and exterior caulk are fitted and finished neatly, so the window looks like it belongs to the house.
Hardware adjusted and tested
Locks, latches and sash balances are set so each window opens smoothly and closes tight against its seals. A window that is easy to operate gets used and cared for, which helps it last.
Signs your windows are ready to be replaced
Fog between the panes
Haze or water spots trapped inside double-pane glass mean the seal has failed. One unit can sometimes be reglazed, but when several are going, replacement is usually the better value.
Soft or dark wood at the sill
Press a screwdriver into the bottom corner of the frame. If it sinks in, water has been getting behind the paint for a while.
Condensation on the frame itself
Single-pane aluminum windows from the 1970s and 80s conduct cold straight through, so the frames sweat and drip all winter. Weatherstripping won't fix that.
Drafts you can feel
A cold draft with the window fully locked often points to a warped frame or a sash that no longer meets its seals.
Sashes that won't stay open or won't lock
Broken balances can be repaired. Frames that have twisted out of square generally cannot.
How a replacement job runs
- 1
Consultation and measurements
We look at every window you are concerned about, check the frames and sills, and talk through your options at your own pace. There is no pressure to decide that day.
- 2
A written quote
You receive a free quote broken out by window, with the install method and any trim or rot work listed separately. We also explain our flexible payment options, and where the city requires a permit, we pull it.
- 3
Ordering
Your windows are built to the measurements we took. We confirm the delivery date with you and schedule the install around it.
- 4
Install day
We lay drop cloths, remove the old units one at a time and set each new window before moving to the next, so the house is never left wide open. Most installs are finished in a single day.

Walkthrough and care notes
Before we leave, we operate every sash with you, clean up the debris and haul away the old windows. We also show you how to keep the tracks and weep holes clear, which does more for a window's life than anything else.
What affects the cost of replacement windows
Two quotes for the same number of windows can be far apart, and the reasons are usually concrete. We price each opening on its own and tell you where the money goes, so nothing changes once work begins without your say.
- Size and style
- Large picture windows, sliders and casements each cost differently, and custom shapes cost more than standard rectangles.
- Frame material
- Vinyl is the most economical and needs little care. Fiberglass and wood-clad frames cost more and offer different strengths in finish and stability.
- Retrofit or full-frame
- Full-frame replacement involves more labor and trim work, so it costs more. It is the right choice when the old frame is damaged.
- What we find underneath
- Rotted sills or framing have to be repaired before a new window goes in. We photograph it and price it separately before any work goes ahead.
- Access and glass type
- Second-story openings that need ladders or staging add time, as do tempered or specialty glass where code requires it.
Window replacement questions
Something not covered here? (253) 264-0720
Can you just replace the glass instead of the whole window?
Often, yes. If the frame and sash are sound and only the sealed glass unit has failed, a new glass unit is a sensible repair. We will tell you if that is the case. Replacement makes sense when the frame itself is the problem.
Do I have to replace every window at once?
No. Many people start with the windows in the worst shape and do the rest later. We can match styles and finishes so the house still looks consistent as you go.
Which frame material lasts longest with the least upkeep?
Vinyl and fiberglass both hold up well in damp weather and never need painting. Fiberglass is stiffer and more stable in large sizes. Wood-clad gives a warmer interior look but asks for more attention over the years. We will help you weigh what matters most to you.
What warranty comes with new windows?
Our window replacement comes with a lifetime warranty. We explain what it covers when the job is complete, and keeping weep holes and tracks clean helps the windows perform as intended.
How messy is install day?
Less than most people expect. We protect floors and furniture near each opening, work one window at a time and clean up before we leave. Old windows and packaging go with us.
Can I spread out the cost?
Yes. We offer flexible payment options and are glad to go over them during your free quote.
